Title: Forced transfer system of steel tube
Inventor: SATOU KATSUTOSHI
IPC: B65G54/02
Filed: 1979-02-19
Abstract: PURPOSE: To increase the power to suck steel tubes for an apparatus provided with multiplicity of electric magnets along the line of the skid-rail, exciting said magnets successively to generate a moving magnetic field giving the driving force towards the direction of a slanting surface, by forming a tapered upper end for the magnet pole of the electric magnet.  
     CONSTITUTION: The electric magnet is composed of the coil 11, main magnet pole 12 (a) auxiliary magnet pole 12 (b), magnetic frame 13, non-magnetic board 14, stand 15 and the upper end of the magnet pole 12 is forming a tapered surface against the upper surface of the skid rail 1 to the direction to transfer steel tubes. Comparing the magnetic sucking power between the point A and B, the magnetic sucking power for the point B must be greater since the distance between the steel tube 10 and magnet poles is shorter for the point B and magnetic resistance is smaller and the magnetic sucking power will be greater. Thus the steel tube will be transferred without failure, to the next magnetic pole B by the excitation of the next magnet not halting at the point A.

Title: Rotor for centrifugal separator

IPC: B04B5/02
Filed: 1994-02-15
Abstract: PURPOSE:To prevent stress from converging into corner parts and extend the life of a bucket by forming a through hole in a wall part of a bucket supporting and receiving part parallel to an axial direction of an arm pin. CONSTITUTION:A bucket is fixed in a rotor of a centrifugal separator which separates blood in a blood bag. A through hole 53 is formed in the wall face of a supporting and receiving part 51 of the bucket 5. In this way, the corner parts are eliminated from the supporting and receiving part 51, and parts where stress converges and stress is very high are thus eliminated. As a result, since other parts where the stress value is low can receive the centrifugal load, the stress is lessened and cracking scarcely occurs. Consequently, the bucket is prevented from being broken and its life is prolonged.

Title: Autofocusing camera provided with interval photographing function
Inventor: KATAOKA HIROYUKI
IPC: G03B17/40
Filed: 1990-01-31
Abstract: PURPOSE:To evade that appropriate photographing can not be executed and to prevent a useless image blurring preventing action by inhibiting photographing by an image blurring prevention means in the case of interval photographing even though image blurring preventing photographing is selected. CONSTITUTION:When a focusing state is obtained by an aurofocusing action in the case of selecting the image blurring preventing photographing (IS mode), a blurring quantity on a range-finding sensor 16 is detected and a shutter time is set to be in place in the smallest blur circle based on the blurring quantity. However, in the case that interval photographing is designated by an interval timer circuit 41, the IS mode is cleared and ordinary photographing, for example, photographing in a program mode is executed. Since a tripod is used in the case of interval photographing, it is needless to perform the prevention of image blurring and then the useless image blurring preventing action is prevented.
